Anti-radiation Air-to-Air Missile

But if the pilot doesn't even know whats coming for him, he surely also doesn't know when to turn off the radar isn't it? Thats what they are using
to advertise the R-27P, as a stealth missile.

As for using a active radar seeker over heat seeker on a BVR missile, is it because that heat seeker are only more effective at tail engagement and
not that great when the missile is coming at the opposite direction of the target?

There was an active seeker in development for the R-27 family, however this never achieved IOC. Active Radar Homing would = ARH. Some of the
confusion is arising due to ARMs, or anti-radiation missiles such as the HARM, being confused with ARHs, which are active radar homing missiles, not
anti-radiation homing.

The Chinese have received exported R-27s, and also have some locally produced missiles in the PL-10, PL-11 and PL-12. PL-10 and PL-11 are based on the
Aspide missile bought from Italy in the 80's, which is a missile based on the AIM-7, so SARH seeker. PL-10 got accredited, but never produced if I
recall correctly, whereas PL-11 did. PL-12 is a locally produced ARH missile, similar to AA-12, but apparently has improved kinematics.

For R-27 stocks, the Chinese definitely have AA-10A and AA-10B, and pictures seem to confirm at least AA-10E (though the pictures I've seen on the
web have the seeker cap on, but it is a fairly distinctive shape. Some websites claim this is an active AA-10 variant, but like I said in my previous
post, I'm pretty sure this never became operational). If China have the short burn variants, it is logical to assume they may have the long burn
variants as well, but I haven't seen anything on the web to confirm this, though some of the pictures of Flankers suggest that the missiles indeed
have the sustain section on them.

From your Su-30MKI walkaround link, those are AA-10A missiles. Long burns have a slight step in the sustain section, which these don't, so definitely
AA-10A. AA-10Cs are substantially bigger. AA-10E and F have a sharper head that houses the seeker. I'll see if I can find a picture to illustrate
better.

That's what I'm talking about when I say there are some websites that are wrong. That one, and the Chinese one you link to are classic examples. The
Chinese military website definitely shows what I believe to be an AA-10E passive radar homing missile (and illustrates what I mean about the seeker
head shape being sharper than the AA-10A and C shape).

The AA-10 active seeker had a number of problems. Another seeker was in development at the same time, and this evolved into the AA-12. So there was no
need to continue development of the AA-10 active variant. Though with the range advantage that the Chuck offers, an active variant may now prove
useful.

I'd say the red stripes are covers as well, likely over the fusing mechanism. Black stripes, like the ones you can see on the R-73 there, indicate
training rounds.

Your ranges are interesting, the missile bodies are the same for the all similar variants (ie AA-10A,B and E for the shorter range, boost only
missile, and AA-10C,D and F for the longer range, boost and sustain missile). So kinematically, ranges should be identical. The only variation will be
in seeker detection capability. Is this what your figures represent?

hmmm..
As far as as I know the IAF has R-27R1/T1/RE1/TE1 where the T1/TE1 variants are SARH while the R1/RE1 are IR.So thats all from Alamo AA-10A to
AA-10D.

As per this site theIAF has purchased insane amounts of R-27 R1/T1s(exceeding 1100 missiles; possibly as many as 1400~) while moderate amounts of R-27
RE1/TE1s

SIPRI (Stockholm International Peace Research Institute) reported that 300 R-27R1/T1 air-to-air missiles were ordered by the Indian Air Force in 1995
and all 300 missiles were delivered in the same year. SIPRI reported that 1140 R-27E missiles were ordered in 1996 and 250 were delivered by 2001.
SIPRI also reported that 1140 R-27R1/T1 missiles were ordered from Ukraine in 1996 and 304 were delivered by 2001. As per the annual UN conventional
arms register, the Indian Government reported it had purchased 40 R-27ER1 and 36 R-27ET1 missiles in 1999 and 20 R-27ER1 and 20 R-27ET1 missiles in
2000. Source

Here's a few pics(somewhere in the middle) of the MiG 29B carrying what is claimed to be the SARH R-27RE1

China is right, your designations are around the wrong way. And it is unlikely that a Mig-29B would carry AA-10A or C as they don't have a fire
control radar, thus defeating the purpose of a SARH missile.
